Kids on Segway -

It was a fine day and off to the local school grounds we ventured.



Clarinda showing off her Segway skills!



And here's Isabella going for a cruise along the sports field.

Setton-Nossiter Park - Videos

Here are a couple of experimental videos done by strapping a video camera to the fender of the Segway.

And of course, the Little Black Dog (LBD)  aka Betty, features during random scenes within the videos!
Most of the track could be done with the i2 tires, but, it's more fun with the 'fatties' on!

This is a definitely a fun track to do again! Hopefully next time we'll get our hands on a helmet-cam of some sort, bearing in mind that in several places the branches hang kinda low. Come to think of it, it would be interesting to find out what wireless coverage there is down there.


Part I -



Part II - Yes, this is a narrow track! In a couple of places there is only a few inches to spare. Of course having LBD leading the way helped to keep us on track! :-)



Well, that's that for now!

Breaker Bay - Wellington, New Zealand

Type: Sandy beach; Walking track

Wheels: x2

Grade: Medium

Breaker Bay is another one of those hidden secrets around Wellingtons eastern bays. It features a sheltered beach at one end for swimmers and sunbathers (and the occasional nudists!), at other end is a popular dive entry point.  The car park near the Southern entrance to the bay is a great spot  from which one can 'chill out'  and watch the ferries and leisure boats go in and out of Wellington harbor.

Much of the beach is made up of fine, wheel eating sand and can be quite taxing on the batteries, not to mention, interesting to glide through! Patience and good balance are important as a momentary lapse of attention can be painful.

This was shot from the car park and gives and 'over view' of the beach and the path leading up to the lookout.

One the interesting features here is the 'hole' in the rock which can be seen in the following clip.

Getting around on the sand was a real struggle for the Segway, chewing through a 'bar' per kilometer, but no problem for the Betty, the Little Black Dog, seen recharging at the top of the lookout.

Also a the top we found these guys watching over the entrance to Wellington harbor.

And here's a view from top........

And....Segway at rest!

Wakely Road, Newlands

Type: Walking Track

Wheels: i2 or x2

Grade: Easy

One of the greatest joys of having a Segway is being able to explore alternative ways and routes to get around. Wakely Road offers a scenic short cut down to the Ngauranga Gorge interchange, (1.5 km vs 2.4km going along the bicycle path next to the motorway).

The steep descent ahead and gravel all the way.

Looking back to where we came from...somehow it looks steeper from this angle!

Red Rocks - Part I

Wellington's South Coast is an outdoors persons playground and home to the South Coast Marine Reserve and Red Rocks Scientific Reserve. The Marine Conservation Centre gives access to both Red Rocks and the Te Kopahau Reserve, and offers the first views of the city from air or sea. It is full of wild life and costal birds as well as little blue penguins and fur seals, the fur seals congregate around Red Rocks (where the rocks are really red!) Activities out there range from walking and diving to four-wheel driving, and now .... Segway off-roading ;-)

One of the challenges of the South Coast is the ever changing landscape and weather, the track is never the same and seems to change every time you look away! This makes it a place where off-roaders, be they mountain bikes or 4x4s go for to play. And the perils are many, there is soft sand that eats wheels and sharp shards of hard rock that cut into your hands and tires, not to mention the wind! The wind that can sneak up on you starting as a gentle breeze into one that will literally blow you away.

Of course this makes it the ideal place to test some of the capabilities of the Segway and the x2 tires.

Known as Pariwhero (Red Rocks) to the local iwi, this was popular place for fishing, paua collection and harvesting Bull Kelp. There is a legend about how Maui stained the surrounding rocks with his blood as bait for his hook prior to catching Te Ika a Maui - the North Island. Another legend tells us that the red of the rock comes from the blood of Kupe who had wounded himself on the surrounding paua.

Kids on Segway

Here are some photos of the kids on the Segway, only took  a few minutes to teach them, and for obvious reasons they were confined to playing within Moonbeam. [Click on the images to get a larger picture]


Isabella in action 

Clarinda takes control

and Catalina joins in the fun!

If they can do it, anyone can!

Catch up

Been a very, very busy week for me! A lot of unexpected events had unfolded and I just haven't been able to keep up with everything!

Back to blogging real soon now.

How it Works - Segway Smart Motion™ - The science behind the technology

When Dean Kamen unveiled the Segway® Personal Transporter (PT) on ABC's Good Morning America, he described the machine as "the world's first self-balancing human transporter." When you look at the machine in motion, you get an idea of what he's talking about. Unlike a car, the Segway PT only has two wheels, yet it manages to stay upright by itself.

To move forward or backward on the Segway PT, the rider just leans slightly forward or backward. To turn left or right, the rider simply moves the LeanSteer frame left or right.

HOW DYNAMIC STABILIZATION WORKS
The ability to balance on its own is the most amazing thing about the Segway PT, and it is the key to its operation. To understand how this system works, it helps to consider Kamen's model for the device—the human body.

If you stand up and lean forward so that you are out of balance, you probably won't fall on your face. Your brain knows you are out of balance, because fluid in your inner ear shifts, so it triggers you to put your leg forward and stop the fall. If you keep leaning forward, your brain will keep putting your legs forward to keep you upright. Instead of falling, you walk forward, one step at a time.

The Segway PT does pretty much the same thing, except it has wheels instead of legs, a motor instead of muscles, a collection of microprocessors instead of a brain and a set of sophisticated tilt sensors and gyroscopic sensors instead of an inner-ear balancing system. Like your brain, the Segway PT knows when you are leaning forward. To maintain balance, it turns the wheels at just the right speed, so you move forward. Segway calls this behavior dynamic stabilization and has patented the unique process that allows the Segway PT to balance on just two wheels.

THE BRAINS AND THE BRAWN
The Segway PT is controlled by an intelligent network of sensors, mechanical assemblies, propulsion, and control systems. The second you step on, five micro-machined gyroscopic sensors and two accelerometers sense the changing terrain and your body position at 100 times per second – faster than the brain can think.

Segway PTs use a special solid-state angular rate sensor constructed using silicon. This type of gyroscopic sensor determines an object's rotation using the Coriolis effect on a very small scale.

Simply put, the Coriolis effect is the apparent turning of a moving object in relation to another rotating object. For example, an airplane trying to travel in a straight line can appear to turn because the Earth is rotating underneath it.

The Segway PT has five gyroscopic sensors, though it only needs three to detect leaning forward or backward (termed “pitch”), leaning to the left or right (termed "roll") and steering to the left or right (termed “yaw”). The extra sensors add redundancy, to make the product more reliable. All of this leaning and steering information, as well as information from additional tilt sensors, is passed on to the brain of the device.

The brains and brawn are made up of two identical and redundant sets of microprocessor-based electronic controller circuit boards, batteries and motor windings that operate together and share the load of driving the wheels. The Segway PT has a number of additional onboard microprocessors. The vehicle requires this much brain power because it needs to quickly make precise adjustments to keep from falling over. If one controller board (or it’s associated battery, motor windings or wiring) breaks down, the other set will take over all functions so that the system can notify the rider of a failure and shut down gracefully.

The microprocessors run an advanced piece of software that controls the Segway PT. This program monitors all of the stability information coming from the gyroscopic sensors and adjusts the speed of the electric motors in response to this information. The electric motors, which are powered by a pair of rechargeable lithium-ion batteries, can turn each of the wheels independently at variable speeds.

When the PT leans forward, the motors drive both wheels forward to keep the PT from tilting over. When the PT leans backward, the motors drive both wheels backward. When the rider moves the LeanSteer frame to turn left or right, the motors drive one wheel faster than the other, or if traveling slowly enough, drive the wheels in opposite directions, so that the Segway PT rotates (steers). When under way, the Segway PT will generate precisely the right radius of turn so that your lean is balanced by the centripetal acceleration generated by the turn.

Just Thinking of Pimping my Ride - SegVator® SegTrax™.

OK, so I not quite sure why I would need to get one of these, but I want one! 8-)
The prototype SegVator SegTrax --- the *all* terrain mod for your Segway, go where you couldn't/wouldn't before! SeVator have come up all sorts of good stuff for the Segway, including the SegPlow for those colder climates.

I'd like to know how far you could actually go with the standard Lithium-Ion battery packs. Pr does it have a different power source?

Gliding Around Paraparaumu

Aerial view of Kapiti Island

On Sunday, while of the kids were lost somewhere in SecondLife I decided to take a quick glide around. Today I tackled two of the steepest streets in know of in Paraparaumu, Panorama Drive and Riwai Street. A what day it was! ( Just a day for a daydream, just could not get that song out of my head!)

Looking down on Paraparaumu from the top of Panorama Drive

Not missing a beat (or growling if you prefer) the Segway just glode along allowing me the luxury of enjoying the sights and the glorious weather that day. 

Aboves is a view of Kapiti Island, a huge bird sanctuary set aside for the protection of native plants and animals. It is located 5km west of the township of Paraparaumu. Humans activity on the island is kept to a minimum and all visitors have obtain permits from the Department of Conservation (DOC) before they can set foot on the island.

But unlike other reserves (marine or otherwise) Kapiti Island is close enough to be easily accessed, this makes it an excellent place to be able to see birds that may not been usually seen on the mainland. Maybe one day, I'll get to take the Segway there! :-)

Coming down the steep hills was interesting, for some silly reason it is not as scarry going up than it is down.  A quick glide up to the water tower atop of Riwai Street and then back down thru Kaitawa reserve before going home for dinner.

And a song to sign off .............

A Bit of Fun - Riding a Segway on a BMX Track

Just for a bit of fun I took the Segway and Booper down to Ian Galloway Park, in Wilton, Wellington.

Once upon a time this area used to be known as the Wilton or Western Tip, and close in 1973.

View Larger Map

Today it boasts five sportsfiields used for ruby during winter and summer sports such as softball and soccer. It also has a BMX track and a dog exercise area.

Nothing utlra challenging for the Segway, but definitely a good place to take beginner to practice and learn. It was also a good place to zip around.  Even Booper a bit of work out chasing the Segway around the track.

Taking on some of those climbs was reminder/re-enforcement that tackling climbs with a Segway is very, very different than when you take on the same with another other vehicle. It is not momentum that gets you up (or down) but making use of the torque provided by the electric motors. And when you get it wrong, the 'Stick Shake Warning' (shakes the handlebar and make growling noises)  comes on to tell you.

Come down is very much like doing the same in a 4x4, you let the engine control the descent and just gently steer when you have to.

Off the Beaten Track#2 Seton-Nossiter Park Newlands

Tucked away deep in the middle of the Newlands-Woodridge-Paparangi suburbs of Wellington is 30 hectares of a protected natural reserve. Originally named Belmont Gully it was changed before the turn of the century to Seton-Nossiter park.

There are 3 'entrances' to this area from Mark Avenue, from Bushland Grove and from Colchester Crescent. On this expedition we decided to take the Colchester entrance. As luck would have it, this proved to be the most challenging of the three being both steep and exposed to the harsh icy winds we were having that day.

A view as we headed down the steep and rocky track....... fortunately the x2 tires are well suited to this steep track. I am constantly impressed with the way that the Segway navigates along the narrow track! Altho one disadvantage is the one must watch out for low hanging branches and stuff (ouch! a few times).

It was easy to get lost in thought down there, tucked away from all signs of the civil world not too far above us. And yet all we could hear (apart from the occasional sounds of the Booper crashing around the bushes) where the birds in trees and the whisper of a gentle breeze.

While we took a break this little fellow came along and kept us company for a while. Nice thing about the Segway is that it is relatively quiet and the native life doesn't seem to mind us gliding by.


At the middle of the park, there is a clearing where there are park benches and access to the Bushlands Road entrance.

Going up towards the Bushland Groveentrance again gave us some great views of part of the park below.

A view from the top towards the Mark Avenue, Paparangi entrance.

Looking across at Woodridge.

Having enjoyed that track, so rather than return to we went back the way we came, back down to the depths of the valley below.

A bit of Fun - Riding a Segway on a Motorcross Track

Here's something I need to do, ride my Segway on  supercross track. Just have to find one near by!
